10. 10 “Recycling”

11. 11 Current State “Recycling” Definition Re-purpose – new use with no changes Re-purpose – new product with only physical changes Re-use – wear another year Re-use – local charity or fashion shop Re-use – ship outside USA/EU

12. 12 Current State “Recycling” Definition Recycle – chemical additions / no chemical changes Recycle – minor chemical changes Recycle – major chemical changes

20. 20 EVERYONE MUST KNOW SUPPLY CHAINS  Newspapers  Plastic Water Bottles  Plastic Other Bottles  Office Paper  Aluminum Cans  Metal Cans

21. 21 EVERYONE MUST KNOW THEIR SUPPLY CHAIN  Designer – Art  Designer – Manufacturing  Yarn Supplier  Fabric Supplier  Fabric Prep  Dyer  Fabric Finishing  Cut and Sew  Garment Maker  Transportation  Retailer  Recycler  Consumer / Disposer

22. 22 EVERYONE MUST KNOW THEIR SUPPLY CHAIN pre-consumer recycled material (post-industrial): Proportion, by mass, of recycled material within a product that has been recovered or diverted from the solid waste stream after the manufacturing process. Excluded is reutilization of materials such as rework, regrind, or scrap generated in a process and capable of being reclaimed within the same process that generated it. For examples of what may and may not constitute this type of material, refer to the US Government Federal Trade Commission

23. 23 EVERYONE MUST KNOW THEIR SUPPLY CHAIN pre-consumer recycled material (pre-industrial): Included is reutilization of materials such as rework, regrind, or scrap generated in a process and capable of being reclaimed within the same process that generated it. There is not a formal definition isnce it is a moving target. Fiber Yarn Fabric Dyed Fabric Finished Fabric Garment Cuttings Garment Seconds

24. 24 EVERYONE MUST KNOW THEIR SUPPLY CHAIN post-consumer recycled material: Proportion, by mass,of recycled material within a product that has been recovered or diverted from the solid waste stream after consumer use. For examples of what may and may not constitute this type of material, refer to the US Government Federal Trade

25. 25 Current State “Recycling” Re-purpose – new use with no changes Washing car with t-shirt Using old towels for spills Storing Christmas decorations

26. 26 Current State “Recycling” Re-purpose – new product with only physical changes Rags for commercial sale Bunny stuffings Pillow stuffings Car trunks - nonwovens

27. 27 Current State “Recycling” Re-use – wear another year Greatest savings in all areas? Unemployment Food Crop Increase

28. 28 Current State “Recycling” Re-use – local charity or fashion shop Does it reduce production? Material not sold? More disposal

29. 29 Current State “Recycling” Re-use – ship outside USA/EU Social concerns Health and safety Landfills Pollution

30. 30 Current State “Recycling” Recycle – no “chemical” changes Chop and melt material Re-extrude Loss of physical properties – Molecular weight – Molecular structure – Color

31. 31 Current State “Recycling” Recycle – chemical additions / no chemical changes Anti depolymerization Agent Dyeing Fire Retardants

32. 32 Current State “Recycling” Recycle – minor chemical changes Polymerization agents Grafting New monomer addition

33. 33 Current State “Recycling” Recycle – major chemical changes Depolymerization to basic monomers Creation of new monomers

34. 34 Biggest Problem Textile Manufacturing, Apparel, and Retail are Complicated

35. 35 Current State “Recycling” Global Recycled Standard v3 Textile Exchange and Stakeholders The Global Recycled Standard is an international standard that provides third-party certification of the recycled content of products by verifying the chain of custody from the recycler to the final product. The Standard also specifies environmental and social requirements for manufacturing, including chemical use.

43. 43 Polyester

44. 44 Polyester Pre and Post Consumer Mostly bottles Physical (melting) and re-extruding Minor chemical changes Depolymerization (Teijin Process) Typically 50% recycled content

45. 45 Polyester

46. 46 Polyester

47. 47 Polyester Problems Color – yellow to white that may require bleaching or can not use for whites, satins, first quality Dyeing – inconsistent batch to batch can cause redyes which use energy, chemicals, and water Dyeing – more dye can be used to achieve the same shades (30%) Contamination – PVC introduced from labels and wrappers

48. 48 Nylon Pre and Post Consumer Mostly carpet and preconsumer Physical (melting) and re-extruding Minor chemical changes Depolymerization Typically 50% recycled content
